## `name`{% #name %}

**Type**: `STRING`**Provider name**: `name`**Description**: Immutable. The name of the hub. Hub names must be unique. They use the following form: `projects/{project_number}/locations/global/hubs/{hub_id}`

## `organization_id`{% #organization_id %}

**Type**: `STRING`

## `parent`{% #parent %}

**Type**: `STRING`

## `policy_mode`{% #policy_mode %}

**Type**: `STRING`**Provider name**: `policyMode`**Description**: Optional. The policy mode of this hub. This field can be either PRESET or CUSTOM. If unspecified, the policy_mode defaults to PRESET.**Possible values**:

- `POLICY_MODE_UNSPECIFIED` - Policy mode is unspecified. It defaults to PRESET with preset_topology = MESH.
- `PRESET` - Hub uses one of the preset topologies.

## `preset_topology`{% #preset_topology %}

**Type**: `STRING`**Provider name**: `presetTopology`**Description**: Optional. The topology implemented in this hub. Currently, this field is only used when policy_mode = PRESET. The available preset topologies are MESH and STAR. If preset_topology is unspecified and policy_mode = PRESET, the preset_topology defaults to MESH. When policy_mode = CUSTOM, the preset_topology is set to PRESET_TOPOLOGY_UNSPECIFIED.**Possible values**:

- `PRESET_TOPOLOGY_UNSPECIFIED` - Preset topology is unspecified. When policy_mode = PRESET, it defaults to MESH.
- `MESH` - Mesh topology is implemented. Group `default` is automatically created. All spokes in the hub are added to group `default`.
- `STAR` - Star topology is implemented. Two groups, `center` and `edge`, are automatically created along with hub creation. Spokes have to join one of the groups during creation.
